"Association of Daily Necessities" is a comprehensive theoretical course. This course guides students to observe real-life daily necessities, which have different shapes due to their different uses, and this triggers rich associations among students. In this course, students can freely choose the way to express themselves. From the students' homework, it can be roughly divided into two parts: one is painting expression, and the other is decorative making. In teaching, I focus on two aspects of guidance. First, when observing the same object, different angles and positions can be exchanged for observation. Due to the different observation angles, different associations will be generated; Second, even observing the same item from the same angle can also generate different associations. An interesting phenomenon occurred in class: since the range of daily necessities is very broad, many students found it difficult to determine what they wanted to represent. Finally, I categorized the daily necessities simply for the students, helping them to determine their representation objects.
